Yup...that's why I suggested "fast cure" it is solid in 24-36 hrs...
Make sure everything is where you want it, because in a week it will be there for good...Thing about the slow cure, is it is still workable with acetone so you can clean up any boo boos you might have...
If you got the regular cure, give it a week it'll be all done even if it is underwater. The stuff will cure underwater, but the guys at 3M couldn't gaurentee it's non-toxicity unless it is cured...It would probably be fine in a couple of days, but that's entirely up to you...
We have put live crab on it in 2 days before during the season, and didn't have any dead loss from it...that's been my experience with it...
